To all whom it nmy concern.-

Be it known that I, ALFRED V. DU PONT, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefulRail-Chair or Tic-Plate for Street-Bailroad Rails, which nvention isfully set forth and illustrated in the following specification andaccompanying drawlngs.

The object of this invention is to make a strong, cheap, and light Chairor tiepIate, the metal for which ean be rolled ina rolling-mill intoflat bars, thickened at suitable points for lugs, and then sheared todcsired lengths for the necessary blanks, said blanks then onlyrequiring the thickened logs to be struck up for tie-platcs and themetal bent to a box Shape for any desired height of such plate orcliair.

The invention consists of the form of structure hereinafter describedand claimed.

In the accompanying drawings, Figure 1 shows a blank of the special formrequired with the necessary spilte-holes punehed in its ends. Fig. 2shows a tie-plate formed from one of said blanks by having clamping-lugsfor clamping the lower ilanges of the rails struck up from the thickenedparis or blank lugs of the metal shown in Fig. 1. Fig. 3 shows a chairof box shape bent from a tie-plate of suitable length to a suitableheight for clamping` the rails at a desired level.

In said figures the several parts are indicated by letters as follows:In Fig. 1, A A indicate the protrusions or blank logs thickened up fromthe rest of the metal, B B, Constituting the whole blank. In Fig. 2, A2A2 indicate (No model.)

of the rolls at such points as itmaybe desired to form the blank logs AA, said lugs will be formed, diagonally place-d or staggeredH onopposite sides,at proper intervals on said bars. Said bars can then besheared as they come from the rolls, or at any convenient time, betwecneach couple or seresof blank lugs,w-hen each piece of bar so cut will bea whole blank read'y to be converted, as hereinbefore explained, intoeither a tie-plate or Chair, as may be desired. I do not confine myself,however, to the sole method of rolling said articles.

Heving thus fully described my said railchair or tie-plate, as of myinvention I claim- As a new article of manufaeture, a rail-chair i'formed, as and for the purposes set forth.
